This invention relates to nozzles of various kinds and classes, and particularly to devices used in conjunction with syringes, and especially devices used in injecting fluids of various kinds and classes into the body of a person, and more particularly to what are known as urethral and vaginal syringes; and the object of the invention is to provide a nozzle structure for devices or apparatus of the class specified involving dual Cl1&111l36ISfl.1-

ranged longitudinally of the nozzle and havindependentdischarges at the free end of the nozzle whereby a fluid may be injected through one chamber or passage and dis 1 cl'iarged through the other chamber or passage; a further object being to provide means for controlling the admission and discharge of fluids through the separate chambers or passages; a still further object being to provide ports opening outwardly through the sides of the nozzle adjacent the discharge end thereof and communicating with the separate chambers or passages therein; and with these and other objects in view, the invention consists in a device of the class and for the purpose specified, which is simple in construction, eflicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol- 3% lowing specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views:

Fig. 1 is a diagrammatic view illustrating one form of my improved nozzle, and inclicating the method of its use.

ig. 2 is a longitudinal, sectional view through the nozzle shown in Fig. 1 on an enlarged scale.

Fig. 3 is a section on the line 33 of Fig.

2; and,

Fig. 4 is a perspective and sectional view of a modified form of nozzle which I employ.

In the construction shown in Figs. 1 and 2 of the drawings, I provide a nozzle 5 composed of relatively soft rubber, rendering the entire nozzle structure flexible, facilitating its many uses. This nozzle is fashioned to form two independent chambers or passages Serial No. 512,879.

6 and 7, subdivided by an intermediate partitionwall 8. The passages 6 and 7 extend longitudinally of the nozzle and open outwardly through the rounded end 9 thereof in discharge ports (is and 7 a. It is also preferable in some uses of the nozzle, to provide other ports 10 and 11 in the side walls of the nozzle 5 adjacent the discharge end 9 and communicating with the passages 6 and 7 respectively.

The other end of the nozzle 5 terminates in diverging tubes 12 and 13, the passage 6 opening into the tube 12 and the passage 7 into the tube 13 as clearly seen in Fig. 2 of the drawings; Hard rubber, metalor other couplings 14 and 15 areadapted to beconnected with the tubes 12 and 13 to facilitate the attachment of flexible tubes 16 and 17 with the nozzle tubes 12 and 18.

In the constructionshown in Fig. 1 of the 7 drawings, the flexible tube 16 leads to a source of supply which may constitute a fluid tank or container, or in fact, the tube16 may be directly coupled with a fluid discharge nozzle. But, in said figure, the tube is shown attached to the lower end of a rubber water bottle 18 containing a suitable fluid adapted to be discharged through the nozzle 5. Mounted on the tube 16 is a snap valve 19 of conventional form employed to control the flow of fluid to the nozzle 5. A similar valveQO is mounted on the tube 17 to control the transmission of fluid therethrough. I Inthe diagrammatic illustration in. Fig. 1 of the drawings, the tube 17 is shown leading to a basin into which 35 the fluid maybe discharged, but this receptacle may constitute a container of any kind or class or a discharge, such for example as a toilet bowl. a

In the use of the nozzle, it. will be under- .90 stood that after the same has been injected into proper position and with the valve 20 closed, the valve 19 may be opened top ermit the flow of fluid into and through the chamher 6 of the nozzle and into the organism of the body to be treated. At any time during this process, the valve 20 may beope'nedto relieve internal pressure, permitting the discharge of the fluid through the tube 17, this operation. taking place with the valve 19 10a opened or closed as may be desired or required.

In some cases, when an internal wash or cleansing is required and where an unlimited supply of fluid is available, both valves '19 and 20 may be left open after an initial amount of the fluid has been injected into the body so as to provide a constant inflow and outflow of the fluid as will be apparent. In

many cases, body ailments of various kinds and classes are treated by the injection of warm water at a temperature governed by means apart from my invention. In such treatments, a relatively long inflow and dis charge of the water is necessary, and with my device, such treatment may be performed without building up internal pressure and causing discomfort to the patient.

In Fig. 1 of the drawings, I have shown a slight modification, which consists in providing a nozzle 21 composed ofhard rubber,bakelite or other rigid material such as employed in the construction of nozzles commonly used in syringes of various kinds and classes. The nozzle 21 has two admission tubes 22 and 23 'at one end thereof communicating with independent chambers or passages 24: and 25 extending longitudinally through the nozzle and opening outwardly through the discharges 26 and 27 at the free end 28 of the nozzle. The side walls of the nozzle have other ports 29, only one of which is shown, which are similar to the ports 10' and 11 ofthe nozzle shown in Figs. 1 and 2. The ends of the tubes 22 and 23 are provided with beaded tips 30, facilitating the attachment of flexible tubes 16a and 17a; therewith, said device being similar to the tubes 16 and 17. Projecting collars 31 on the tubes 22 and 23 serve to limit the inward movement of the flexible tubes 16a and 17a.

It will also be apparent that instead of using my improved nozzle with an intake tube and a discharge tube, both chambers or passages of the nozzle may be used as intake passages, especially for fluids of difl'erent characteristics. v

It will be understood that my invention is not limited to any particular shape, form or contour of the nozzle, and especially with respect to the discharge end thereof and the form of the shank. My improved nozzles may be constructed along the lines of other devices of this class consistent with the par ticular use or uses for which the same is in tended. It will also be apparent that the dis chargeports 10,11 and 29 need not necessarily be employed, said ports providing for lateral as well as longitudinal discharge. Va-

rious changes in and modifications of the constructlon-hereln shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificingits advantages. 7

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A colonic irrigation nozzle of the class described comprising an elongated tubular body of flexible material, an integral partition dividing said body into independent inlet and outlet ducts extending longitudinally thereof, said ducts o-penin outwardly through the extreme tip end 0 the nozzle in independent passages of the same size and substantially of the same cross sectional area as said passages, and means for coupling independent tubes with the other end of said nozzle in such manner as to communicate with the separate ducts thereof.

2. A colonic irrigation nozzle of the class described comprising an elongated tubular body of flexible material, an integral partition dividing said body into independent inlet and outlet ducts extending longitudinally thereof, said ducts opening outwardly through the extreme tip end of the nozzle in independent passages of the same size and substantially of the same cross sectional area as said passages, means for coupling independent tubes with the other end of said nozzle in such manner as to communicate with the separate ducts thereof, means on said independent tubes for controlling the transmission of fluid into and through the ducts of .said nozzle and other ports communicating with the separate ducts of the nozzle inwardly of the discharge end thereof.

I In testimony that I claim the foregoing as my invention I have signed my name this 28th day of January, 1931.
